In a shocking discovery, biologists discover dragons! Dragon geneticists determine that flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b). They suspect that the two genes are linked in one of the autosomes. They mate a true-breeding, flame-eyed, burbling female with a true-breeding, blue-eyed, whistling male. They then mate a pair of offspring. Please draw punnet square to support your explanation Part One: Assuming dragon genetics follows the same rules as fruit flies, what ratio of genotypes would you expect if the genes were not linked? (Remember you are crossing FfBb x FFB6).

In a shocking discovery, biologists discover
dragons! Dragon geneticists determine that flame
eyes (F) are dominant to blue eyes (f) and burbling
(B) is dominant to whistling (b). They suspect that
the two genes are linked in one of the autosomes.
They mate a true-breeding, flame-eyed, burbling
female with a true-breeding, blue-eyed, whistling
male. They then mate a pair of offspring.
Please draw punnet square to support your
explanation
Part One: Assuming dragon genetics follows the
same rules as fruit flies, what ratio of genotypes
would you expect if the genes were not linked?
(Remember you are crossing FfBb x FFBB).
Part two: If the genes are linked, which of the F2
genotypes would occur at a lower frequency than
would be expected if the genes were not linked?
Analyze the pedigree below and determine if the
trait is inherited as autosomal dominant,
autosomal recessive, X-linked dominant, X-linked
recessive, or Y-linked. Justify your answer.
